> Currently Python TNonblockingServer uses select.select to monitor the IO of
> all existing connections. The value of file descriptors monitored by select()
> is limited to be lower than _FD_SETSIZE_ (1024). Any file desciptor higher
> than 1024, when passed into select.select, will trigger the "fd out of range"
> error.
> Switching to select.poll can solve this problem. However, as noted in the
> official documentation, select.poll is not supported in all operating system.
> We should also check whether the current system has poll in the select
> module, and use poll if it's available.
